"Everything happens at the @glblctzn show. Even photobombs of our Prime Minister @justinpjtrudeau while I try to take a photo with his gorgeous wife Sophie! #globalcitizen #zoomin #spotjustin," Morin captioned the photo.

Trudeau photobomb aside, both Sophie and Maripier looked lovely, sporting high ponytails for the event.

For the festival, which aims to help stop the spread of AIDS, malaria and tuberculosis, Grégoire Trudeau wore a black dress by Canadian label Madame Moje. The frock featured lace sleeves and a peplum detail at the waist. Justin, on the other hand, kept things casual in a Global Citizen tee and a pair of jeans.

While posing on the blue carpet, Sophie added a black leather jacket by Mackage.
